Why FTTx PON
• Reduced OpEx: Passive components network
– High reliability → Fewer truck rolls
– Decreased power expenses
– Faster installation times
• Reduced CapEx:
– 1 - 64 subscribers per fiber
– 1 Fiber +N transceivers vs. N Fibers + 2N transceivers
• Increased Revenue Opportunities:
– Multi-service: Data, Voice (TDM & VoIP), Video (RF Overlay & IPTV)
– Video:
• RF Overlay: Traditional RF broadcast services to deliver basic and premium channels
• IPTV: IP-based technology for video-on-demand and premium services
• Scalability:
– CO Equipment shared → New subscribers added easily as the network grows
– Bandwidth is shared → Existing subscriber bandwidth can be changed on
demand
